EIS-0285-SA-133: Supplement Analysis

Transmission System Vegetation Management Program

Vegetation Management for the Hanford-Ostrander Corridor from structure 126/1 through structure 146/4. Right of way width averages 312 feet. BPA proposes to remove unwanted vegetation along the right-of-way, access roads, and around tower structures along the subject transmission line corridors. Approximately 20 miles of right-of-way will be treated using selective and non-selective methods that include hand cutting, mowing and herbicide treatments. Access roads and tower sites will be cleared using selective and non-selective methods that include hand cutting, mowing and herbicide treatments. Vegetation management is required for unimpeded operation and maintenance of the subject transmission line
